Maybe Otis Taylor is a local figure in a certain community. He could be known for his integrity and this phrase is something he often says to encourage others to be truthful. For example, in a small town where he's involved in community affairs, he might use this statement to promote honest communication and transparency among the people.
The sudden strange noises make it scary. Like when you're in a small enclosed space like an elevator and there are unexplained creaking or groaning sounds, it immediately sets an uneasy mood.
Well, if Otis Taylor is a creative person, like a musician or a filmmaker, 'truth is not fiction' might be his way of saying that he wants to capture the real essence of things in his art. He might be against creating works that are just for the sake of entertainment without any real substance. His art could be a medium to convey real emotions, real stories, and real situations, rather than fabricating something that has no connection to reality.
Otis met his end in The Walking dead comic because he got caught in the crossfire during a zombie attack. His fate was sealed when he couldn't escape in time.
I'm not sure exactly who Amos Otis is. It could be a person from a particular profession or a character in a lesser-known story. Maybe he's someone whose story is yet to be widely shared and discovered.
There was a group of friends who decided to try the elevator game as a dare. They entered the elevator at midnight. As they went through the sequence of floors, they heard eerie noises. When they finally reached the 'destination' floor, the elevator doors opened to a pitch - black corridor. One of the friends got so scared that they immediately pressed the ground floor button and the elevator took them back to safety. It was a spooky experience that they would never forget.
